Provided is a frame body used in a cell of a redox flow battery with which it is possible to improve heat dissipation from an electrolyte in a slit and minimize an increase in temperature of the electrolyte. A frame body used in a cell of a redox flow battery, wherein the frame body is provided with an opening formed on the inside of the frame body, a manifold channeling the electrolyte, and a slit connecting the manifold and the opening and forming a channel for the electrolyte between the manifold and the opening. The slit has, in a cross-section orthogonal to the direction in which the electrolyte is channeled, a pair of side walls facing each other, and has a narrow part, in which the spacing between the side walls decreases in the depth direction, in at least some of the depth direction of the slit. |
